1 Claim. 1

My invention relates to a hitch for anchoring implements.

An object of my invention is to provide an arrangement which will rigidly maintain the space between a driving pulley attached to a tractor and the like and a driven pulley which operates any type of implement having rotary parts.

A further object of my invention is to provide a structure which maintains such rigidity so that the driving belt engaging such pulleys will be in constant alignment and tension.

A further object of my invention is to provide such an arrangement which can be collapsed after use and including arrangements for hitching the same to a tractor for drawing the unit to desired locations.

A further object of my invention is to provide an adjustable arrangement which will include means for making smaller lateral adjustments, and which will further include means for more extreme adjustments as well as providing means for adjusting the pulley drives so that they will operate from either side of the driving or driven arrangements.

With these and other objects in view, my invention consists in the construction, arrangement, and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:

Figure l is a side elevation of the unit,

Figure 2 is a plan viewof Figure 1,

Figure 3 is a further plan view showing the adjusting members in a laterally changed position,

Figure 4 is a detail,

Figure 5 is a detail, and

Figure 6 is a detail of the hinges.

I have used the character III to designate a normally flat channel member and the character I I a further channel member, such channel members having the flanges I3 and I4 welded thereto (see Figure 6) with such members being pivoted at I5. Attached at I6 (see Figure 4) beneath the channel member ID is a substantially U-shaped yoke IT. The members are hinged as explained at each end thereof, and attached at I3 to the channels III are a pair of further channels I9 which extend forwardly and are attached at 20 (see Figure 5) to the bearings 2| which receive a shaft 22 upon which are rotatably mounted the wheels 23.

Attached at 24 to the members I9 are a pair of further channels 25 which extend angularly 2 upwardly and are crossed at 26 and which terminate in the ends 21. Suitable bracing members 28 and 29 are attached between the members I9 and 25 to brace the same. The channel I I includes the bolts 30 to which are attached the further channels 3| which are braced by means of the further bolts 32, 33, and 34. The members 3| are bolted at 35 to a transverse member 36 which is angle'shaped and which includes a series of equally spaced openings 31, and it will be noted that the member 36 is pitched at an angle greater than 90 from the members 3 I. Attached to the member 35 are a pair of extending ears 38 to which are pivoted at 39 the upwardly extending side flanges 49 of the U-shaped member 4| to which are attached a series of transverse angles 42 at the bottom thereof.

In using the arrangement, the implement which is indicated by the character 43 in this case being a hammermill grinder, is bolted at 44 and 45 to the ends 21 of the members 25 and the channels IS, the pulley of the grinder being indicated by the character 46. The attachment at 45 can be adjustable for allowing slight angular positioning of the implement. The drive pulley of the tractor is indicated by the character 47, and the belt which engages the pulleys 46 and 4'! is indicated by the character 48. The tractor 49 which is to drive the grinder is driven forwardly so that the forward wheels 50 thereof will lie within the member 4|, the small angles 42 then penetrating into the ground, thereby holding the arrangement firmly, and the wedge chuck 5| is placed ahead of the wheels 50. The arragement is then ready for operation, and it will be noted that the driving engagement of the belt and pulleys is thus uniformly maintained due to the entire fixed rigidity of the structure which maintains the pulleys in fixed position.

The openings 31 in the member 36 permit any lateral smaller adjustments of the tractor with respect to the unit so that the belts can be properly aligned.

For more extreme adjustments the members 3| can be placed so that they occupy the lower positions as shown in Figure 3 with the cross piece 52 which is provided to brace the members 3| being placed at the opposite angle as clearly shown, this change being readily made by merely unbolting the various bolts 30, 32, 33 and 34. This will permit of a much greater lateral adjustment, and the angular positioning of the member 36 allows a pulley 41 on one side of the tractor or other driving unit to drive a further pulley 46 at the opposite side of the driven unit,v

the belt 48 passing angularly across the anchor hitch and as shown in Figure 3, the driven unit which can be positioned angularly if necessary before being bolted. The upper ends of the brace members 25, which brace members are relatively thin are bent or flexed slightly before bolting to allow for the adjustable positioning of the member 43.

For transporting the unit after use, the members 3|, etc. are swung on the pivoting points l5 backwardly until they occupy the dotted position shown in Figure 1 and the tractor drawbar 53 is placed within the yoke 11, and the unit can then be drawn wherever desired. It will be understood that any kind of driving machine can be employed as well as driven arrangements, It-

will now be also seen that I have provided the advantages mentioned in the objects of l my in-'-' vention with further advantages being readily apparent.

Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claim any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

I claim as my invention:

An anchor hitch for implements comprising a framework, a further framework, said frameworks being pivoted to each other, one of said frameworks adapted to be rigidly attached to an implement having a rotatable mechanism, said further framework including a platform for receiving tractor wheels thereon, said further framework including an adjusting member to which said platform is attached, said adjusting member including a pair of attached lengthened braces, attachment of said braces at either side of said framework providingmeans for-positioning a belt drive with respect to the tractor and said implement, said framework including a hitch member attached thereto, whereby said framework can be'drawn when collapsed together.
